ATTORNEY April 26, 1960 w. J. LIVSEY ETAL WINDOW CONSTRUCTION 3Sheets-Sheet 3 Filed Sept. 17, 1957 INVENTORS H V ww n w m E .4 UM Q MWwmfi This invention relates to a window-sash construction and moreparticularly to the weatherproo'fingof window sashes of the type whereinthe stiles of the s ash a epi'viorally mounted to and between supportsslidably mounted in guides in the window frame whereby a single sashor-an upper or lower sash of the window maybe opened by rotativemovement While, at the same time, providing for a vertical upward andsliding movement of the sash. f

It is the primary object of the present invention to provide improvedmeans arranged along the stiles of the sash which co-operate with meansarranged along'thesash supports to seal the space therebetween when thesash is fully closed so as to ettectively prevent the passage of air,moisture and dust and other foreign elements therebetween.

It is another object of the invention to provide an improvedweatherproofing means for window sashes of the rotative type which notonly acts to prevent the passage of air, etc., between the same and itssupports but also acts as a stop so as toproperly seat and lock the sashin a Patented Apr. 26,, 1966 zontal axis, each of the sashes may betilted or turned so that access may be had to the outer side of thesashes from the inner side of the window, as will be apparent fromFig,3. v,

According to thepresent invention, there is arranged along the outeredge of each of the stiles4 of each of the sashes, a pair of elongatedweatherproofing strips 7 and 8 which are substantially L-shaped incross-section so as to provide a bottom leg portion 9 and an upwardlyextending leg portion 10. This bottom leg portion consis'tspreferably ofa double thickness of the material i.e. the ma terial is folded uponitself to form this substantially V- shaped bottom leg so as to providea resilient lip portion 12.

v The strips are made preferably of a relatively thin, flat, strip ofmetallic material having resilient characteristics. One is disposed toeither side of each of the pivotal cong nections 5 and extends therefromto the outer ends of the respective stiles 4. The strip' on one side ofthe pivotal connection 5 of each of the stiles is disposed opposite't'o'that positioned on the other side of the pivotal connection verticalposition in its frame when the window is moved- 6 to its fully closedposition. 7 It is a further object of this invention toprovide animproved window construction of the rotatable sa'sh type wherein thereis provided means for'holding the sash and supports therefor underspring tension so as to prevent rattling or the sash in the supports,which means also efficiently and elfectively seals the space between thesash and the supports when thewindow is rotated to its closed position.v 1 I Various other objects and advantages of this 'vjention will bemore apparent in the course of'the fol 'w ng .specification, and will beparticularly pointedou' iithe ap pendedclaims. Y f In the accompanyingdrawings, there isshown forthe purpose of illustration, anembodirne'ntwhichour invention may assumeinpractice.

Referring morepa'rticularly to the drawings,"the improved's'ashconstruction of the'present invention may be incorporatedin anyconventional type double-hung win 'dow frame 1 having oppositelydisposed guideways 2 and 3 with upper and lower sashes,'respectively"Eachof the sashes comprises a pair of side stiles 4 which are 'pivotallyattached centrally thereof,as at-S, to the vertical supportfor a purposehereinafter to be described. 5;

There is arranged in the outer edge of eachof the stiles 4, a pair ofspaced-apart longitudinally extending slots 01' grooves 13 and 14-. Thebottom leg portion 9; together with the lip portion 12 carried therebyis disposed in the I slot or groove l3'on one. side of the pivotalconnection 5, and the bottom leg portion 9 of the strip disposed orwedged on thetopposite side of thetpivotal connection is disposed orwedged in the'slot or groove 14011 the op posite side thereof so thatthe vertical leg portions 10 extend inopposite directions, one towardthe inside of the sash andthe other toward the outside thereof, as morec'learly shown in Figs. 3 and 6 of the drawings.

on the inner side of each of the supporting members 6, there is arrangeda longitudinally extending groove or slot 15 so as to provide stopshoulders or ledges 16, 'and' 1'7 therealong with which the free edges18 of the weatherstrips 7 and 8 cooperate in a manner presently to bedescribed. a I

When the sashes fare in their fully rotative closed positions, as shownin Fig. 1, 4, and.5,.it will be seen that the freeedges 18 of each-ofthe strips 7 and 8 lie in the respective grooves or slots 15 in thesupporting members 6 and abut the respective shoulders or ledges 16 and17 therein. That is to say, that, the free edge of the strip 7 on oneside of the pivotal connection 5 of'each of the sashes will abut theshoulder or ledge 16 of the respective grooves 15 and that the free edgeof the strips will abut the shoulder or ledge 17 on the opposite side ofthe pivotal connection so as to etfectively seal the space between theouter edge of the stiles 4 and the supporting members 6.

It will be seen that these free edges 18 of the stripsnot only lie inthe grooves or slots 15 so as to effectively seal the space between thesupporting members and the stiles ofthe sash but also co-operate withthe shoulders of ledges 16 and 17 so as to provide a stop for furtherrotative movement'of the sash. That is to say, the free edges of thestops will abut and seat against-the shoulders'16 and 17 so as toprevent continued rotative movement of the window past its fully closedposition. -Also, the strips 7 and 8, due to the resilientcharacteristicsthereof, hold the sash in the supporting members undertension so as to prevent any lost motion or rattling of the sash inthesupports. When the sash is moved or swung to an:

open position, as shown in Fig. 3, and the dotted lines of Fig. 2, theleg portions 10 of the strips 7 and 8 spring outwardly from the stilesand are disposed angularly relative thereto and act to frictionally holdthe sash in its open position. I

Between the twosashes there is positioned a frame 2 having a screen 21arranged therewith. This, frame 21 is arranged in the frame 1 betweenthe supporting members 6 with the sides of the screen frame arrangedslidably in grooves 22 positioned between the guideways 2 and 3 so thatthe screen may be raised or lowered. Thus, it will be seen this screencan be disposed opposite the opening of either the upper or lower sash,as desired.

As a result ,of our invention, it will be seenthat there is not onlyprovided a window construction which is simple and economical in itsmanufacture but at'the same time efficient and effective in its use.
